Which Way Does the Filter Go?

1. Ultra Fine White Filter:  Remove the old filter first and discard.  Clean the area with a dry cloth.  The white filter should be placed into the filter area with the mesh-side facing in. The tab should be at the top.
2. Grey Foam Washable Filter:  This filter should be placed on top of the white filter.  When properly inserted, you should only see the grey foam filter and a small section of the white tab.
